Explanation:

Answer 2

C) 2(20)

Explanation:

In a football game there are 2 teams playing against each other so there are 2 possible winners in a game as either of the 2 teams can win the game. So there are 2 ways to make prediction of winner for a game.

Since, there are 20 football games in total, and predictions of winner per each game are 2, so the possible predictions for 20 games would be 2 x 20

Hence, 2(20)=40 different predictions would be possible for 20 football games.
